The 'Donald Trump Untreated Syphilis Theory' gained traction on social media, particularly on X (formerly Twitter), in early 2024 after photos surfaced showing red sores or blisters on the former President's hands. Internet sleuths and armchair doctors began speculating that these marks were consistent with secondary syphilis, leading to a wave of satirical posts and medical charts being compared to news footage. While many experts suggested the marks could simply be skin irritation or paper cuts, the 'untreated syphilis' narrative became a viral trope used by critics to mock Trump’s health and erratic behavior. The meme serves as a prime example of how visual cues in political photography can spark rapid-fire internet conspiracies and satirical commentary.
